Steadwing — Cursor Plugin

AI-powered root cause analysis for Cursor. Analyze errors, stack traces, and incidents directly from your editor.

What it does

This plugin adds the run_rca MCP tool to Cursor, powered by Steadwing. When you encounter an error, the AI agent can send it to Steadwing for deep root cause analysis and return a link to the full incident report.

Installation

Install from the Cursor Marketplace, or add manually to your project's .cursor/mcp.json:

{
  "mcpServers": {
    "steadwing": {
      "command": "npx",
      "args": ["-y", "@steadwing/mcp-server"],
      "env": {
        "STEADWING_API_KEY": "your-api-key-here"
      }
    }
  }
}

Setup

1. Get your API key from https://app.steadwing.com/organization
2. Set the STEADWING_API_KEY environment variable or enter it when prompted by Cursor

Plugin components

Usage

Once installed, the Cursor agent will automatically suggest Steadwing RCA when you:

• Paste an error message or stack trace
• Ask for help debugging a failing test or service
• Mention "root cause analysis" or "Steadwing"

The tool sends your error (and optionally relevant source files) to Steadwing's API and returns a URL where you can view the full analysis.
